Why did my edited Excel files on Android get deleted on my desktop?

I have installed office 360 in my android phone and One Drive to enable me to access & edit my files outside my desktop. I am using same office 2013 in my desktop.
I have edit my excel file in android phone thru One Drive using excel (office 360) then when i open my file in my desktop all the content on the edited sheet are all gone including formatting

yup its really strange and it happen twice, i thought i might have done something. Good thing then was i have another copy of the file, and after copying the file I deleted the old one thinking that it will be alright, but now I'm in hell formats and formulas and the accounting figures are all gone..... is this one of One Drive bugs?
